gas flow MMscf/day = MSm3/day
is it the same?
std. cubic feet in imperial units, M is mega (1000) so MM (1000*1000) = million metric SI units, the prefix M is mega with a factor of 10^6 = million but again I am seeing field units in metric million as MMSm3/day Any ideas? thanks

Re: gas flow MMscf/day = MSm3/day
Quote:
In the SI, qualifiers like S for standard or N for normal can't be mixed with unit symbols (although it is a VERY common misuse.) A prefix may not be used alone and attaches to the unit, so Mm³ would be cubic megameters. (I am sure that is not their intent). Roman numerals are never used. If you want to indicate a million cubic meters, you could use cubic hectometers hm³ However, I asked NIST a similar question a few years ago, and they recommended not using "standard" or "normal" gas volumes at all, but to use moles instead, with an appropriate prefix.

1 mmscf= .028 mmscm

Re: gas flow What is KSm3/d & m3Vn
And so what is KSM3/D. Is it different from the MSM3/D which I understand means million cubic meter per day.
What does the unit M3Vn mean

Re: gas flow MMscf/day = MSm3/day
Afraid you have "Mega" defined incorrectly.
M or Mega is 10^6, or 1,000,000 k or kilo is 10^3, or 1,000 For the record: m is milli, 10^3, or 0.001 (1/1,000) Problem is that m also means metres.

Re: gas flow MMscf/day = MSm3/day
MMscf/day = MSm3/day
The M in the meters is probably Mega (10^6) the MM in cf is probably form the roman MM = 10^6

Re: gas flow MMscf/day = MSm3/day
From Schlumberger:
MMscf 1. n. [Production Testing] ID: 11227 Abbreviation for million standard cubic feet, a common measure for volume of gas. Standard conditions are normally set at 60oF and 14.7 psia. See: million standard cubic feet
